Excellent work!

It is the tendency of the vanadium metal and the oxides of lower oxidation state to oxidize to V2O5 when they are developed under oxygen control.
But this also happens although the kinetics of this process can be slow?

I recommend poster 16, it was worked with vanadium, some interest could arise for both

Thanks for the question, according to your question, when we growth the films with a low percentage of oxygen, we obtain metastable phases of oxides composed of VO2, VO and V2O5 in a lower proportion, however, when the percentage of oxygen is low it is less likely It is transformed into V2O5 since it is a structure controlled in its growth from nucleation and not just a superficial layer of V2O5, so it can protect the other sub-oxides inside the film.
